[QUOTE="Pharbach, post: 1046844, member: 77675"] Had a #2 cylinder misfire (P0302) history. Recently got the truck, so replaced plugs & wires. Problem still existed, so I threw a coil pack at it. Same problem, but now I get a "Bank 1 System Too Lean" (P0171). Cleaned MAF sensor, no help. Searching for PCV. I know it's near the firewall on drivers side, but where? OBD Live Data shows REL FRP (Fuel Rail Pressure running between 36PSI @ 41PSI. Is this in norms, and is the fuel pressure variation normal? I'm actually suspect #2 fuel injector is causing the misfire and Bank too Lean codes. Truck runs okay I guess, but I can sense a shuddering and loss of power due to the engine missing on and off. Any help would be great! =Paul [/QUOTE]
